{Due to|Because of|As a result of|On account of|Resulting from|As a consequence of} their availability, low {cost|price|expense}, non-toxicity and tunability, polymeric carbon nitrides (CNx) represent {one of the most|probably the most|just about the most} {attractive|appealing|desirable|eye-catching} {materials|supplies|components} classes for the {development|improvement} of {fully|totally|completely} sustainable photo(electro)catalytic systems for solar-driven water splitting. {However|Nevertheless|Nonetheless|Even so|On the other hand|Having said that}, the {development|improvement} of CNx-based photoanodes for visible light-driven water oxidation to dioxygen is rather {challenging|difficult}, {particularly|especially|specifically} {due to|because of|as a result of|on account of|resulting from|as a consequence of} {issues|problems|concerns|troubles|difficulties|challenges} {related to|associated with} photoelectrode stability and {effective|efficient|successful|powerful|productive|helpful} coupling {of the|from the|in the|on the|with the|of your} light absorber with water oxidation catalysts. Herein, a triadic photoanode comprising a porous TiO2 electron collector scaffold sensitized by CNx coupled to a molecular cobalt polyoxometalate (CoPOM = [Co4(H2O){2|two}(PW9O34)2]10─) catalyst is reported. {Complete|Total|Full|Comprehensive} water oxidation to dioxygen {under|below|beneath} visible (λ > 420 nm) light irradiation is demonstrated, with photocurrents down to {relatively|fairly|comparatively|reasonably|somewhat} low bias potentials (0.{2|two} V vs. RHE). {Furthermore|Moreover|In addition|Additionally}, polyethyleneimine (PEI), a cationic polymer is shown to act as {an effective|an efficient} and non-sacrificial electrostatic linker for immobilization {of the|from the|in the|on the|with the|of your} anionic CoPOM onto the negatively charged surface of CNx.
